FIREPROOF WALL.

SPECIFICATION forming part of Letters Patent N0. "792,593, dated June 20, 1905.

Application filed July 16,1903. Serial No. 165,788.

To @ZZ wtont /t Hefty concern:

Beit known that LABRAHAM L. A. HIMMEL- WRIGHT, a citizen of the United States, residing at New York, county of New York, and State of New York, have invented certain new and useful Improvements in Eireproof Walls, fully described and represented in the following specification and the accompanying drawings, forming a part of the same.

The object of the present invention is to provide an improved concrete wall or partition for buildings in which the concrete shall be lirmly anchored to the metal members and to produce a structure of great strength for its thickness, while quickly and cheaply huilt.

A construction embodying the inventionin the preferred form will now be described in connection with the accompanying drawings, forming a part of this specification, and the features forming the invention then speciiically pointed out in the claims.

In the drawings, Eigure l is a side elevation, partly broken away, of a wall embodying the invention. Eig. 2 is a horizontal section of the same. Eig. Sis a vertical section of the same with the concrete partly broken away to show the construction.

In erecting the wall metal studs A are set up at suitable distances apart, these studs preferably being channelirons, as shown and as usual in such constructions, and after these studs are set up and suitably secured to form a metal framework the concrete B is tilled in to form the wall in which the studs A are embedded. As thc concrete is filled in from below horizontal metal rods C are inserted atintervals, these rods being passed through holes in the studs A and being spaced at suitable distances apart to give the required anchorage for the concrete against sidewise strain. After the wall is completed the surface may be covered with a facing D, of plaster or similar plastic material, as shown in Eig. 2, or the surface may be left uncovered or finished in any suitable manner on the outside with brick or stone, according to the character of the construction in connection with which the invention is applied. The concrete is preferably filled in to form the wall by erecting temporary'wood centerings on opposite sides of the studs A, filling in the concrete for a short distance from the bottom, putting in the rods C on the concrete filled ,in,.then increasing the height of the centering, filling in more concrete and putting in rods, &c., until the wall is completed.

It will be seen that the construction is very simple and readily built, while at the same time the rods C securely anchor the concrete to the studs A, producing a wall that may be made quite thin, while securing the desired transverse strength. IVith channel-irons, as shown, the concrete blocks between the channel-irons are anchored at one end by the ianges of the channel-irons, and such anchorage may be sufiieient for this end of the concrete blocks unless the studs be widely separated. The channel-irons, however, afford no anchorage for the other ends of the concrete blocks between the channel-irons, and it is found in practice that the concrete is liable to break away from the rear or unfianged side of the channel-irons. My invention provides anchorage for the concrete on this side of the channel-irons and greatly strengthens the construction.

I have shown the length of the rods C as substantially that of the distance between the studs A and arranged so that alternate rods in a stud pass through substantially the width of the body of concrete on opposite sides of the stud, so that an anchorage is secured for practically the whole body of concrete, which enables the desired strength to be secured with the studs spaced well apart. It will be understood, however, that if the studs are placed closer together the rods may extend only a short distance on each side of the studs if channel-irons be used, the more important feature in such case being the anchorage of the ends of the concrete blocks on the rear or untlanged side of the channel-irons.

That I claim isl. A wall or similar vertical structure consisting of vertical metal studs,`a concrete tilling forming a solid wall between the studs,

and rods between the studs forming an anchorage for the concrete and passing through the studs, said rods being formed in sections of such length that they may be inserted between adjacent studs and passed through the studs after the studs are in position, substantially as described.

2. A wall or similar Vertical structure consisting of vertical channel-irons, a concrete iilling forming a solid wall between the ehannel-irons, and rods between the channel-irons forming an anchorage for the concrete and passing through the channel-irons, said rods being formed in sections of such length that they may be inserted between adjacent studs and passed through the studs after the studs are in position, substantially as described.

3. A wall or similar Vertical structure consisting of vertical metal studs, a concrete lilling forming a solid wall between the studs, and rods embedded in the concrete filling' and not secured to the framework but held in position by engagement with the studs to form an anchorage for the concrete, said rods being' vformed in sections of such length as to be inserted between adjacent studs and engaged with the studs after the studs are in position, substantially as described.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
